I am working on a Stag which sat in a barn for 30 years, I got carried away scraping off the underseal in the wheelwells. It was cracked and I expected to find some rust underneath. To my surprise, all I found was the original paint, with patches of primer (red oxide, I presume). No sign of rust at all. Of course, I scratched the paint while I was scraping, and now I have no rotection against stones etc. I put a coat of primer on to protect the metal while I was away - last chance I had to work on the car was November. Now I wonder what you guys would recommend to protect the wheel wells. I thought stone chip. I found a U-Pol stone chip kit on Amazon, but my local parts places don't seem to know what stone chip is - they want me to use 3M Schutz - seems more like underseal than stone chip. Any advice?
While I am on - I have some self etching primer. Does that only work on shiny new metal or can it be applied over sections with some old paint?
